a reporter surveys people leaving an ice hockey game and asks them whether they agree that the rink is old and rundown and should be destroyed to make room for a new Shop Smart Store. Why might the data this reporter collects be biased?
first of all i don't know what is biased and im so confused about this problem grrr.
Obviously, the people who have participated in or watched the game are interested in hockey.
This is a biased sample because it's just one small sample who obviously enjoy ice hockey. It doesn't take into consideration the opinions of others in the community.
Biased means he has already made up his mind which way he wants the survery to go and he has phrased his question in that way.
If he were to rephrase the question in this way, he would probably get better results, even if the data supports his own private view:
"Do you think this rink should be demolished and a new retail store built on this ground?"
